IC 1396 is a large complex of emission and dark nebulosity in the constellation Cepheus. One of the
dark nebulae in the complex has been named the Elephant's Trunk Nebula due to its appearance. Adrian Brown captured this image
of The Elephant's Trunk Nebula in IC 1396 in June 2008. To create the image he captured 15 x 20 minute exposures using a Skywatcher
80ED refractor, William Optics 0.8x focal reducer, Atik ATK16HR ccd camera and an Astronomik 6nm Hydrogen-Alpha filter. The raw
data was calibrated (bias and flat-field) and stacked via Maxim DL. The stacked image was then processed in Photoshop using
Levels and Curves. A light Gaussian Blur filter was used to smooth noise in the dimmest parts of the image.
